Today, eye care teams across the nation are now mimicking the strategy we have spent more than 50 years perfecting.

Our Services

Our ophthalmologists have expertise in a wide range of specialties and work as a team to meet your eye care needs.

Cataracts

Not only is cataract treatment the most frequently performed surgery in the United States, it is also one of the most successful. More than 99% of patients who undergo cataract removal rank their vision as significantly improved. Drs. Hammer, Dierks, Eide, In't Veld, West, and Dickes perform this highly effective procedure.

More Information

Glaucoma

Early detection and treatment is the key to preventing vision loss with Glaucoma. More than three million Americans have glaucoma, but only half are actually aware that this "silent thief" is slowly and without warning stealing away their vision, sometimes without any noticeable symptoms. Drs. In't Veld and Dickes at Ophthalmology LTD specializes in the diagnosis and treatment of glaucoma.

More Information

Pediatrics

Children should have a yearly comprehensive eye exam along with their parents. Many vision problems can be detected early and treated before they become detrimental to a child's development, learning abilities, and every day function. Dr. West of Ophthalmology LTD has 22 years of experience in the evaluation and treatment of children's vision.

More Information

Retina

The retina functions much like the film in a camera, and when film is damaged, so is the picture. Our retinal specialists Drs. Geraets, Thomas, and Atchison  offer comprehensive retinal exams and treatment to protect against diseases such as diabetic retinopathy that can damage your retina and vision.

More Information

Cornea

If a window pane is distorted or marred by imperfections, it is difficult to see out through it clearly. Your cornea is your eye’s window. To keep it clear or to restore it to its proper state, Dr. Eide of Ophthalmology LTD uses his specialty training in corneal diseases to treat dry eye, keratoconus, and other conditions that can cause corneal imperfections.

More Information

Oculoplastics

When your eyelids, eye sockets, or tear ducts malfunction, or a tumor threatens your vision, Ophthalmology LTD oculoplastic surgeon Dr. Hammer can help. Specializing in procedures that restore clear vision as well as a more youthful appearance, Dr. Hammer treats and manages a wide variety of ocular conditions.
